Abstract
Based on the software of ABAQUS, a finite element model was developed in the study of simulating the ultimate tensile strength and failure mode of repaired specimens. To certify the validation of the model, an experimental study was carried out on intact and repaired laminates. The calculated results are coordinate with the tested results very well. Parametric study was conducted on the model to investigate the influence of ultimate tensile strength on changes of scarf ratio, toughness of adhesive, thickness of adhesive, dimension of damage and extra repair plies. The results of the investigation provide insight into the repair design method on hybrid plain woven fabric laminates with penetrate damage.
